Not quite sure how this site works, but here is my problem. I bought a used 011350S Traeger furnace from a friend. I've installed it and when I fire it up it kicks in and runs when I turn the thermostat up, but when it reaches the temperature the thermostat is set at the auger and feed cup motors just keep running and the temperature keeps rising! The light on the side blinks when it reaches the set temp. so its my understanding that its going into pilot mode. Anyone got any ideas?? Any help would be appreciated!

Your description almost sounds like it is working as it should. When you mention setting the thermostat, is that a room thermostat or the furnace thermostat? The furnace should go into high burn mode until the set point of the furnace thermostat is reached. At that point it will pilot until a room thermostat calls for heat or the furnace temp drops below the low limit.

Also, by the way that model number you gave is not the furnace model. That is a solid-state control box for Traeger (aka Pinnacle) boilers and furnaces. I am suspecting that perhaps you have a GBU70 furnace?

When the room thermostat reaches the desired temperature it is not going into pilot mode ...

You are correct it is a GBU070 furnace.It has an old Honeywell mercury wall thermostat hooked to it on two wire thermostat wire. I agree that it is running correct until it reaches the desired temp. in the house and it just keeps running corn in, when i believe it should kick out and run on pilot? The furnace itself has no thermostat setting that i can see. It has three switches pilot cycle time, off/draft/and feed, and pilot fan speed.

Do you have the Manual for the furnace. There is a lot of troubleshooting info in there.

If you don't have an Manual try going on line They might have one here for it to do a a search on stove manufacture in the stove section of this Forum Or go to the old Forum and try there under your stove Name

Good Luck
